I am try to perform an asus p5b-vm bios update so I can slap in a Quadcore proc. The current Bios on the system is American Megatrends ver. 0410-00.ROM. I have found and downloaded the newest version of the BIOS from Asus's website, ok until there.... Problem is when I try to use the EZ flash tool in the BIOS, it says the new bios is imcompatible with the current version. I have downloaded Asus's update utility, same result... I have booted the box into FreeDos and used AMI's flash utility, it says that the BIOS updates successfully, but when I check the version, it's still 0410-00.ROM. I have looked around a bit and it seems that the version of BIOS on this box may be an engineering version. At this point I want to just blow the old version away so I can get Asus's latest BIOS on there.... Anybody have any insight?makohotrod@yahoo.com
